Winter in a village of Mohe, afternoon and white in the yard to play at night to rest when the package to forget the package in the yard (the bag put a iphone, a cottage, a charger, a charge Po) , The next morning to get up when the discovery of small white hair fever, then remember to wrap in the yard, quickly rushed out to pick up the phone call 120, may I ask this phone to save the white? What about the operation of other electronic devices?
Only the charger inside no lithium battery, as long as the structure at low temperature without damage, the charger will remain available.
But three with lithium battery equipment is not easy to say.
General lithium batteries can withstand the minimum temperature of -20 ℃, and Mohe winter average temperature is only about -30 ℃, the lowest temperature or even only -50 ℃! In such a low temperature environment, ordinary lithium batteries can not work; even low-temperature lithium batteries, usually only can withstand -40 ℃ low temperature ... ...
Therefore, in the yard put a night on the phone, charging treasure, etc., will not be able to boot work.
To call the phone, you must first make the phone battery can be restored to the normal working temperature.
As the iPhone battery can not be removed, the battery heating needs to heat the entire phone, the time needs to be relatively long; and cottage machine battery can be removed, you can separate the battery, the rapid recovery of temperature ... ...
Engineer's perspective Analysis of the impact of low temperature on electronic equipment:
For electronic equipment exposed to low temperatures, due to low temperature will change the physical properties of its constituent materials, it may cause temporary or permanent damage to its performance.
1, hardening and embrittlement of electronic equipment materials;
2, in response to the temperature transient, different materials produce different procedures of contraction, and different parts of the expansion rate is different, causing parts to each other to kill;
3, due to increased viscosity, lubricating oil lubrication and reduced mobility;
4, changes in electronic equipment performance;
5, the performance of transformers or electromechanical components change;
6, electronic equipment vibration reduction rigidity;
7, the firmware explosion pill or pill (such as ammonium nitrate, etc.) crack;
8, rupture and cracking, embrittlement, impact strength change and strength reduction;
9, electronic equipment is subject to static fatigue generated by the glass;
10, water condensation and icing;
11, electronic equipment burning rate changes.
The appropriate approach is as follows:
First, the phone will be removed in the cell phone, the phone and battery were put into plastic bags, wrapped good;
Second, the phone and battery together with the plastic bags are placed between 20-40 ℃ (in this range the higher the better) place (such as hot kang pot quilts, under their own armpits, their hands palm ...), the main purpose is to let the battery quickly warming;
Third, as long as the battery temperature to more than zero, you can put the battery into the phone (the phone is still installed in a plastic bag, to prevent the water vapor into the phone failure), and then boot, call.
As long as the appropriate way, the battery heating time will not exceed 5 minutes, usually 1-2 minutes is enough to allow the battery to restore function.
